Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-41721)
The vulnerability allows a remote attacker to perform HTTP/2 request smuggling attacks.
The vulnerability exists due to improper validation of HTTP/2 requests when using MaxBytesHandler. A remote attacker can send a specially crafted HTTP/2 request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
